Struct ContextualizedError 

pub struct ContextualizedError<I> {
    pub input: I,
    pub char: Option<char>,
    pub error: Option<Error>,
    pub context: Vec<(I, &'static str)>,
}

A nom-compatible error type that captures relevant information for the SGML parser.

Fields

input: I

The remaining input when the error occurred.

char: Option<char>

Was a certain character expected?

error: Option<Error>

context: Vec<(I, &'static str)>

The collected context.

Implementations

impl<I: Deref<Target = str>> ContextualizedError<I>

pub fn describe(&self, input: &I) -> String

Returns a string describing this error.

pub fn describe_to<W: Write>(&self, input: &I, f: W) -> Result

Writes the detailed description of this error to the given output.

Trait Implementations

impl<I> ContextError<I> for ContextualizedError<I>

fn add_context(input: I, ctx: &'static str, other: Self) -> Self

Creates a new error from an input position, a static string and an existing error. This is used mainly in the context combinator, to add user friendly information to errors when backtracking through a parse tree

impl<I: Debug> Debug for ContextualizedError<I>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<I> FromExternalError<I, Error> for ContextualizedError<I>

fn from_external_error(input: I, _kind: ErrorKind, e: Error) -> Self

Creates a new error from an input position, an ErrorKind indicating the wrapping parser, and an external error

impl<I> ParseError<I> for ContextualizedError<I>

fn from_error_kind(input: I, _kind: ErrorKind) -> Self

Creates an error from the input position and an ErrorKind

fn append(_input: I, _kind: ErrorKind, other: Self) -> Self

Combines an existing error with a new one created from the input position and an ErrorKind. This is useful when backtracking through a parse tree, accumulating error context on the way

fn from_char(input: I, c: char) -> Self

Creates an error from an input position and an expected character

fn or(self, other: Self) -> Self

Combines two existing errors. This function is used to compare errors generated in various branches of alt.
